Any change in form rather than in essence based on the concept of the present utility model should be regarded as the protection scope of the present utility model.

[0041] In the following description, all directional or positional concepts such as up, down, left, right, front, and back are based on the positions shown in the corresponding drawings. It is only for the convenience of describing the technical solution provided by the present utility model in conjunction with the drawings and simplifying the description, and thus cannot be understood as a special limitation on the technical solution provided by the present utility model.

[0042] Embodiment 1

[0043] Please refer to Figure 1 , Figure 6 , Figure 12 , Figure 13, the present utility model relates to an electric driving device for a switch. The electric driving device 3 is installed on the outside of the drawer seat 1. The described outside refers to that the electric driving device 3 is located outside the shell of the drawer seat 1, rather than integrated inside the drawer seat 1. Specifically, in combination with the attached drawings, the electric driving device 3 is installed on the outside in front of the drawer seat 1, that is, in the direction facing the operator. The electric driving device 3 is used to drive the transmission system inside the drawer seat 1 to act, and then the transmission system drives the switch body 2 to move relative to the drawer seat 1. The electric driving device 3 is a separate device, and it can realize the switching between the fixed state and the detachable state with the drawer seat 1. Usually, the electric driving device 3 is connected to a remote control handle 200. That is to say, the electric driving device for the switch includes the electric driving device 3 and the remote control handle 200, and the two are remotely connected. The remote control handle 200 can control the electric driving device 3 to act, and the electric driving device 3 also needs to be powered on, for example, connected through a plug. When the electric driving device 3 and the drawer seat 1 are in the detachable state, it does not affect the normal operation of the drawer-type switch. It only needs to be manually operated when driving the switch body 2 to move inside the drawer seat 1. The electric driving device 3 includes a slide plate 325 and a signal module 36; the slide plate 325 moves synchronously with the switch body 2, and after the slide plate 325 moves, it triggers the signal module 36 to send a position signal of the switch body 2 to the remote control handle 200; the operator reads the position signal of the switch body 2 from the remote control handle 200.

[0044] As Figure 2 shown, the electric driving device 3 is installed on the outside of the drawer seat 1. A slide rod head 100 protrudes from the electric driving device 3, and the slide rod head 100 cooperates with the switch body 2, that is, when the switch body 2 moves out of the drawer seat 1, the switch body 2 moves synchronously with the slide rod head 100.

[0045] As Figure 3 shown, the electric driving device 3 includes a housing 31 and other components installed inside the housing 31. For example, an interlock module 32, a motor 33, and a gear set 34.

[0046] Continue to see Figure 3 , the drawer seat 1 includes a transmission system for driving the switch body 2 to move inside the drawer seat 1. Usually, the transmission system includes a transmission shaft 11, a drag plate, a rotating shaft, etc. The transmission shaft 11 is driven to rotate, and then drives the drag plate to move. After the drag plate moves, it drives the rotating shaft to rotate. After the rotating shaft rotates, it drives the movement of the switch body 2. Usually, the transmission shaft 11 is driven to rotate by the driving handle of the drawer seat 1 manually. Of course, the transmission shaft 11 can also be driven to rotate by the electric driving device 3 in this solution.

[0047] An indicator 12 is also provided in the drawer seat 1. The indicator 12 is used to display the position state of the switch body 2. Specifically, it reflects the above position state through the rotation angle. The specific description and function of the transmission system in the drawer seat 1 and the indicator 12 can be found in the patent CN206758931U. The indicator 12 in this patent is the transmission member in the patent description, and the transmission shaft 11 is the screw rod in the patent description.

[0048] like Figure 4 As shown, an interlocking module 32, a motor 33, a gear set 34, a drive head assembly 35 and a signal module 36 are arranged inside the housing 31. The interlocking module 32 receives the position state of the switch body 2 by cooperating with the indicator 12 in the drawer seat 1 to control the on and off of the motor 33. The motor 33 is connected to the gear set 34 in a transmission manner, and the gear set 34 is connected to the drive head assembly 35 in a transmission manner. The signal module 36 is used for signal transmission between the electric drive device 3 and the outside.

[0049] Continue to see Figure 3 and Figure 4 The housing 31 includes a bottom plate 311 and a cover plate 312, and the bottom plate 311 and the cover plate 312 are combined to form the housing 31. Usually, the bottom plate 311 and the cover plate 312 are both made of metal plates, and the housing 31 is in a flat square box shape.

[0050] The interlocking module 32, the motor 33, the gear set 34, the drive head assembly 35 and the signal module 36 are all mounted on the cover plate 312. The cover plate 312 is fixedly mounted with the bottom plate 311 by screws. Preferably, the bottom plate 311 has first bent plates on both sides, and the cover plate 312 has second bent plates on both sides. More specifically, a pair of first bent plates are on the left and right sides, and a pair of second bent plates are on the front and back sides. The pair of first bent plates and the pair of second bent plates constitute the four side walls of the housing 31.

[0051] like Figure 5 , Figure 6As shown in the figure, the interlock module 32 includes a bracket 321, a locking engagement rod 322, a sliding rod 323, a locking member 324, a sliding plate 325, a signal switch 326, and an electromagnet 327. The bracket 321 includes a pair of bracket plates which are spaced apart from each other and are fixedly arranged at a fixed interval by a fixed shaft, and the bracket 321 is fixedly installed in the housing 31. The locking engagement rod 322 is slidably arranged on the bracket 321. The locking engagement rod 322 cooperates with the indicating member 12 in the drawer seat 1. The sliding rod 323 is slidably arranged on the cover plate 312. One end of the sliding rod 323 is provided with an elastic member 3231, and the other end is provided with a striking end 3232 which cooperates with the electromagnet 327. The elastic member 3231 is preferably a tension spring. One end of the elastic member 3231 is connected to the sliding rod 323, and the other end is fixedly arranged, so as to provide a driving force for the sliding rod 323 to move towards one side. The direction of the driving force is specifically towards the direction of the drawer seat 1. Since the upper part of the locking engagement rod 322 is clamped with the sliding rod 323, when the elastic member 3231 applies a force to the sliding rod 323, a force is simultaneously applied to the locking engagement rod 322 to make it approach the indicating member 12 in the drawer seat 1.

[0052] The locking member 324 is a lever member. The locking member 324 is rotatably arranged on the bracket 321. An elastic reset member 3241 is provided on the locking member 324, and the elastic reset member 3241 provides a restoring rotational force for the locking member 324. The locking member 324 is used to lock the locking engagement rod 322.

[0053] The sliding plate 325 is also slidably arranged on the bracket 321. Specifically, it is slidably arranged on the outside of the bracket 321. When the electric drive device 3 is installed in place, the sliding plate 325 moves synchronously with the switch body 2. Specifically, a sliding rod head 100 of the sliding plate 325 is connected to the switch body 2 by means of, for example, abutting. In order to ensure the abutting relationship between the two, the sliding plate 325 is acted on by an elastic member to ensure the abutting relationship between the two, that is, to ensure that the two move synchronously in the front-rear direction.

[0054] As Figure 5 、 Figure 6 and Figure 12 As shown in the figure, the signal switch 326 is used to receive the trigger of the locking engagement rod 322 to realize the on-off of the motor 33, and prevent the motor 33 from continuing to operate and burning itself when the switch body 2 is in the locked state.

[0055] As Figure 4 As shown in the figure, the signal module 36 is used to connect with external signals and simultaneously indicate the working state of the electric drive device 3 to the operator, that is, the position state of the switch body 2.

[0056] As Figure 3 、 Figure 7As shown, the drive head assembly 35 includes a fixing plate 351 and a drive head 352. The fixing plate 351 is installed between the bottom plate 311 and the cover plate 312, while the drive head 352 is rotatably arranged on the fixing plate 351. Correspondingly, a transmission shaft 11 is provided in the drawer seat 1. One end of the transmission shaft 11 close to the drive head 352 is provided with a mating head 111, and the mating head 111 is in plug-in fit with the drive head 352.

[0057] As Figure 5 , Figure 6 , Figure 8 shown, the locking and mating rod 322 is usually made of an insulating material, and the main body of the locking and mating rod 322 is in the shape of a round rod. Sliding mating ends 3221 extend outwards on both sides of the locking and mating rod 322, and the sliding mating ends 3221 are used for the sliding connection between the locking and mating rod 322 and the bracket 321. A clamping protrusion 3222 is also provided above the locking and mating rod 322, and the clamping protrusion 3222 is clamped into the sliding rod 323, so as to realize the synchronous sliding movement between the locking and mating rod 322 and the sliding rod 323. One end of the locking and mating rod 322 close to the drawer seat 1 forms three clamping grooves 3223, and the clamping grooves 3223 are used for clamping and mating with the indicating member 12 in the drawer seat 1, that is, when the switch body 2 moves to the separation, test, and connection positions, the clamping grooves 3223 are clamped into the head of the indicating member 12. During the above process, the locking and mating rod 322 moves towards the indicating member 12 by a clamping distance.

[0058] As Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 9 shown, the sliding plate 325 is slidably arranged on the outside of the bracket 321. The sliding plate 325 is usually processed from a metal plate. A sliding groove 3251 is provided on the sliding plate 325, and the sliding groove 3251 is used for the sliding arrangement of the sliding plate 325 to ensure the reliability of the movement. A top plate 3252 formed by bending is also provided at the top of the sliding plate 325, and a position pit 3253 is provided at the bottom of the sliding plate 325. The top plate 3252 is used to drive the microswitch of the signal module 36 to output a position state signal. A sliding rod head 100 is provided at one end of the sliding plate 325, and the part of the sliding rod head 100 protruding from the cover plate 312 contacts the switch body 2 to ensure synchronous movement of the two.

[0059] As Figure 6 , Figure 10 shown, the electromagnet 327 is also installed on the cover plate 312 and corresponds to the sliding rod 323. After the electromagnet 327 is energized, the striking rod 3271 on the electromagnet 327 can strike the striking end 3232 of the sliding rod 323, so as to push the sliding rod 323 to move.

[0060] As Figure 5 , Figure 6 ,Figure 11 As shown, the locking member 324 is processed from a metal plate. An elastic reset member 3241 is sleeved on the transmission shaft of the locking member 324. Preferably, the elastic reset member 3241 is a torsion spring. A convex shaft 3242 is provided on one side of the locking member 324. The convex shaft 3242 protrudes out of the bracket 321 and abuts against the position pit 3253 of the slide plate 325.

[0061] Please continue to refer to Figures 1 to 11 and combine with Figure 12 , Figure 13 , the working process of the interlock module 32 of the drawer-type switch of the present utility model is as follows:

[0062] When the switch body 2 is in the separated position in the drawer base 1, at this time, the engaging groove 3223 of the locking engagement rod 322 and the indicating member 12 in the drawer base 1 are at an angle where they can be engaged. Under the traction of the elastic member 3231, the slide rod 323 drives the locking engagement rod 322 to be engaged with the indicating member 12. Due to the forward movement of the locking engagement rod 322, the oppression on the signal switch 326 is released, and the signal switch 326 switches on and off, cutting off the power supply to the motor 33, and the motor 33 stops rotating. At this time, it is in the locked state.

[0063] In the above locked state, the electromagnet 327 receives a signal and acts. The electromagnet 327 pushes the slide rod 323 backward. Of course, the slide rod 323 can also be pulled manually to act. During the backward movement of the slide rod 323, the acting force of the elastic member 3231 needs to be overcome.

[0064] Since the engaging protrusion 3222 of the locking engagement rod 322 is engaged into the slide rod 323, and the slide rod 323 and the locking engagement rod 322 are in a synchronous movement relationship. When the slide rod 323 moves backward, the locking engagement rod 322 also moves backward. At this time, the locking engagement rod 322 is disengaged from the engaging relationship with the indicating member 12, and because of the backward movement of the locking engagement rod 322, the signal switch 326 is also oppressed to cause its state to switch, and power is supplied to the motor 33.

[0065] At this time, since the switch body 2 is in the separated position, the slide plate 325 that moves synchronously with the switch body 2 is in the corresponding position. At this time, the position pit 3253 below the slide plate 325 corresponds to the convex shaft 3242 on the locking member 324. At this time, the locking member 324 can swing upward and engage with the locking engagement rod 322 by means of a buckle to prevent the locking engagement rod 322 from moving forward.

[0066] As the motor 33 works, the switch body 2 continues to move relative to the drawer base 1, and the slide plate 325 also moves. The position pit 3253 no longer corresponds to the convex shaft 3242, and the convex shaft 3242 is pressed down, thereby releasing the buckle cooperation with the locking engagement rod 322. The locking engagement rod 322 is driven by the slide rod 323 to be close to the indicating member 12 in the drawer base 1.

[0067] The above process only describes one cycle of locking and unlocking of the interlock module 32 in the separated position. For the three positions of separation, test, and connection, there is a cycle of locking and unlocking for each position. Since the working methods are the same, they will not be elaborated further.

[0068] For the switch body 2, one is the entry process through the positions of separation, test, and connection; the other is the exit process through the positions of connection, test, and separation. The cycles of locking and unlocking are the same for both, and the difference lies in the rotation direction of the motor 33, which is controlled by the circuit.

[0069] Such as Figure 14 , a abutting member 300 is installed on the slide rod head 100 of the slide plate 325. The abutting member 300 is fixedly installed on the slide rod head 100 and abuts and cooperates with the switch body 2. That is, when the installation is in place, the abutting member 300 is always in contact with the front side of the switch body 2 to ensure the synchronous movement of the two. That is to say, when the switch body 2 moves in the drawer seat 1, the abutting member 300 always abuts against the front side of the switch body 2 and ensures the synchronous movement of the two.

[0070] Combined with Figure 4 、 5 , in order to ensure the above-mentioned synchronous movement, a spring member is installed on the slide plate 325. One end of the spring member is connected to the slide plate 325, and the other end is fixedly arranged, so as to apply a force towards the switch body 2 to the slide plate 325 to ensure the abutting relationship between the slide plate 325 and the switch body 2. Specifically, the other end of the spring member is connected to the fixing plate 351.

[0071] The abutting member 300 is usually made of plastic. The abutting member 300 is in two pieces, and the two abutting members 300 are spliced and fixed to form a complete abutting member 300. One end of the abutting member 300 close to the switch body 2 is provided with an abutting surface 301, and the abutting member 300 abuts against the front side of the switch body 2 through the abutting surface 301. The abutting member 300 further includes an installation portion 302 and a fastening portion 303. The installation portion 302 is used to connect with the slide rod head 100, and the fastening portion 303 is used to tighten the two abutting members 300 together. The connection between the installation portion 302 and the slide rod head 100, and the tightening of the two abutting members 300 together are all completed by means of threaded parts for fixed installation.

[0072] Such as Figure 15 , a micro switch is provided inside the signal module 36, and the slide plate 325 is used to trigger the micro switch inside the signal module 36 to send a position signal to the remote control handle 200.

[0073] The signal module 36 includes a module housing, which consists of a bottom case 361 and a top case 362. The bottom case 361 and the top case 362 are spliced up and down to form the module housing. Inside the module housing, there are a signal conversion switch module 363 and a trigger assembly 364. The trigger assembly 364 is driven by the top plate 3252 of the slide plate 325 to act. After acting, it triggers the signal conversion switch module 363 to emit corresponding position status signals.

[0074] A first cavity 3611 is provided inside the bottom case 361. The first cavity 3611 is for the signal conversion switch module 363, while the trigger assembly 364 is installed in the second cavity 3621 inside the top case 362. When the bottom case 361 and the top case 362 are spliced, the signal conversion switch module 363 and the trigger assembly 364 are also installed in place accordingly.

[0075] The signal conversion switch module 363 includes a circuit board 3631, a conversion switch 3632, and a plug-in terminal 3633. The conversion switch 3632 and the plug-in terminal 3633 are installed on the circuit board 3631. Among them, the plug-in terminal 3633 is exposed outside the bottom case 361 for easy wiring.

[0076] The trigger assembly 364 includes a slide rod 3641, a slider 3642, and a return member 3643. The slider 3642 is sleeved on the slide rod 3641, and the return member 3643 is also sleeved on the slide rod 3641. One end of the return member 3643 abuts against the slider 3642, and the other end abuts against the inner wall of the top case 362. The return member 3643 provides a return force for the slider 3642.
